Description
Organe d'aération de véhicule automobile Motor vehicle ventilation device
L'invention concerne un système de rafraîchissement de l'habitacle d'un véhicule automobile. The invention relates to a cooling system of the passenger compartment of a motor vehicle.
ARRIERE PLAN DE L'INVENTION Les systèmes de rafraîchissement d'air pour véhicule automobile intègrent le plus souvent un climatiseur pour assurer le confort thermique des passagers positionnés à l'avant et à l'arrière, en établissant dans l'habitacle une température inférieure à la température externe. BACKGROUND OF THE INVENTION Air vehicle air cooling systems most often incorporate an air conditioner to ensure the thermal comfort of passengers positioned at the front and rear, by establishing in the passenger compartment a temperature below the external temperature.
Ces systèmes ventilent de l'air rafraîchi principalement en partie avant de l'habitacle, de sorte qu'ils apportent un confort thermique surtout aux occupants situés à l'avant du véhicule. Les places situées à l'arrière sont moins bien ventilées, de sorte qu'elles sont aussi moins bien rafraîchies. These systems ventilate cooled air mainly in front of the passenger compartment, so that they bring thermal comfort especially to the occupants located at the front of the vehicle. The seats at the back are less well ventilated, so they are also less refreshed.
Pour améliorer le rafraîchissement des places situées à l'arrière, il est connu, notamment du document FR2982533, de nébuliser de l'eau dans les canalisations d'aération de la région située à l'arrière de l'habitacle. Concrètement, les microgouttes d'eau nébulisées sont diffusées avec le flux d'air destiné à l'aération et/ou la ventilation des places situées à l'arrière, de sorte qu'elles s'évaporent en provoquant un abaissement de température du fait de la chaleur latente de vaporisation qui est alors absorbée. Les microgouttes condensées qui se forment au niveau des parois internes des canalisations d'aération sont collectées dans un canal relié au nébuliseur pour l'alimenter en eau, ce qui permet de recycler ces microgouttes condensées. To improve the cooling of the seats at the rear, it is known, including FR2982533, nebulizing water in the ventilation ducts of the region located at the rear of the cabin. Concretely, the nebulized water microdroplets are diffused with the air flow intended for the ventilation and / or the ventilation of the places situated at the back, so that they evaporate causing a lowering of temperature of the fact latent heat of vaporization which is then absorbed. The condensed microdroplets that form at the inner walls of the aeration pipes are collected in a channel connected to the nebulizer to supply water, which allows to recycle condensed microdrops.
OBJET DE L'INVENTION OBJECT OF THE INVENTION
L'objectif de l'invention est de réduire la quantité de microgouttes qui se condensent dans un tel système. The object of the invention is to reduce the amount of microdroplets that condense in such a system.
RESUME DE L'INVENTION SUMMARY OF THE INVENTION
A cet effet, l'invention a pour objet un organe d'aération et/ou de ventilation destiné à être monté dans un habitacle de véhicule automobile en étant connecté à un conduit véhiculant un flux d'air destiné à l'aération et/ou la ventilation, pour délivrer ce flux d'air dans l'habitacle, cet organe comprenant une grille destinée à être traversée par le flux d'air d'aération et/ou de ventilation, cette grille étant équipée
d'un nébuliseur agencé pour délivrer des microgouttes de liquide nébulisé dans le flux d'air d'aération et/ou de ventilation en aval de la grille. For this purpose, the subject of the invention is a ventilation and / or ventilation device intended to be mounted in a passenger compartment of a motor vehicle while being connected to a duct conveying a flow of air intended for ventilation and / or ventilation, to deliver this flow of air into the passenger compartment, this member comprising a grid intended to be traversed by the flow of ventilation air and / or ventilation, this gate being equipped a nebulizer arranged to deliver microdrops of nebulized liquid into the airflow of ventilation and / or ventilation downstream of the grid.
Selon une variante d'exécution de l'invention, l'organe d'aération et/ou de ventilation selon l'invention est disposé au niveau de la partie terminale du conduit véhiculant un flux d'air d'aération et/ou de ventilation. Préférentiellement, l'organe d'aération et/ou de ventilation selon l'invention est disposé au niveau de la partie du conduit véhiculant un flux d'air d'aération et/ou de ventilation débouchant dans l'habitacle. According to an alternative embodiment of the invention, the ventilation and / or ventilation device according to the invention is disposed at the end portion of the duct conveying a flow of ventilation and / or ventilation air. . Preferably, the ventilation device and / or ventilation according to the invention is disposed at the portion of the conduit carrying a flow of ventilation and / or ventilation air opening into the passenger compartment.
L'organe d'aération et/ou de ventilation selon l'invention permet avantageusement de créer un flux de nébulisation hors dudit conduit, directement dans la même direction que le flux d'air d'aération et/ou de ventilation, ce qui favorise l'évaporation des microgouttes de ce flux de nébulisation et réduit voire annule le risque de condensation. The ventilation and / or ventilation device according to the invention advantageously makes it possible to create a nebulization flow outside said duct, directly in the same direction as the aeration and / or ventilation air flow, which favors the evaporation of microdroplets from this nebulization flow and reduces or even eliminates the risk of condensation.
Le flux de nébulisation est ainsi dirigé sur les parties du corps de l'occupant du véhicule quelle que soit sa corpulence et quelle que soit la taille de la zone à traiter. La sensation de fraîcheur liée à la nébulisation en sortie de l'organe d'aération et/ou de ventilation est localisée au niveau du flux de nébulisation. The nebulization flow is thus directed to the body parts of the occupant of the vehicle regardless of its size and regardless of the size of the area to be treated. The sensation of freshness related to nebulization at the outlet of the aeration and / or ventilation device is located at the level of the nebulization flow.
De plus, les microgouttes de liquide nébulisé sont générées directement dans l'habitacle, de sorte que le risque de stagnation de liquide dans les canalisations est écarté. In addition, the microdroplets of nebulized liquid are generated directly in the passenger compartment, so that the risk of stagnation of liquid in the pipes is discarded.
L'invention concerne également un organe tel que défini ci-dessus, comprenant une embase dans laquelle la grille s'emboîte tout en conservant au moins un degré de liberté par rapport à cette embase de manière à être orientable, afin que le nébuliseur s'oriente conjointement avec la grille lorsqu'un utilisateur règle l'orientation de cette grille. The invention also relates to a member as defined above, comprising a base in which the grid fits together while maintaining at least one degree of freedom with respect to this base so as to be orientable, so that the nebulizer s' orients with the grid when a user sets the orientation of that grid.
L'invention concerne également un organe tel que défini ci-dessus, dans lequel la grille et l'embase sont liées l'une à l'autre par une liaison de type rotule lorsque la grille est emboîtée dans l'embase. The invention also relates to a member as defined above, wherein the gate and the base are connected to each other by a ball-type connection when the gate is fitted into the base.
L'invention concerne également un organe tel que défini ci-dessus, dans lequel le nébuliseur est de type piézoélectrique. The invention also relates to an organ as defined above, in which the nebulizer is of piezoelectric type.
L'invention concerne également un organe tel que défini ci-dessus, dans lequel la grille a une forme générale de révolution et porte le nébuliseur dans sa région centrale.
L'invention concerne également un organe tel que défini ci-dessus, dans lequel la grille porte un volet de fermeture rotatif situé en face aval de cette grille, en étant mobile en rotation autour du nébuliseur entre une position d'ouverture pour laisser le flux d'air passer et une position de fermeture pour fermer le passage du flux d'air. The invention also relates to an organ as defined above, wherein the grid has a general shape of revolution and carries the nebulizer in its central region. The invention also relates to a member as defined above, wherein the gate carries a rotary closure flap located on the downstream face of this gate, being rotatable around the nebulizer between an open position to let the flow air flow and a closed position to close the passage of the air flow.

DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION
L'idée à la base de l'invention est de générer les microgouttes d'eau non pas dans le système de ventilation ou de climatisation, mais au contraire en aval de chaque bouche où le flux d'air de ventilation est expulsé. Les microgouttes sont ainsi pulvérisées directement vers l'habitacle, dans le flux d'air de ventilation, de sorte que le risque de stagnation d'eau dans les conduits est complètement écarté. The idea behind the invention is to generate water microdroplets not in the ventilation or air conditioning system, but instead downstream of each mouth where the ventilation air flow is expelled. The microdrops are sprayed directly to the passenger compartment, in the ventilation airflow, so that the risk of water stagnation in the ducts is completely eliminated.
Comme illustré schématiquement sur la figure 1 , l'organe de ventilation selon l'invention, repéré par 1 , comprend une embase 2 qui est solidarisée ou intégrée à un élément 3 de garniture intérieure du véhicule, tel que l'élément d'habillage de la partie arrière de la console centrale du véhicule. As schematically illustrated in FIG. 1, the ventilation member according to the invention, marked by 1, comprises a base 2 which is secured to or integrated with an element 3 of the interior lining of the vehicle, such as the cladding element of the vehicle. the rear part of the center console of the vehicle.
Cette embase 2 qui a une forme de révolution comporte une ouverture centrale 4 formant bouche de ventilation, et elle est connectée à un conduit 6 d'alimentation en air rafraîchi qui est lui-même relié à un réseau de ventilation d'air du véhicule. La surface interne de l'ouverture centrale 4 a une forme généralement cylindrique comportant sensiblement à mi-longueur une portion 7 présentant sensiblement la forme d'une couronne de sphère, de plus grand diamètre que les portions cylindriques 8 et 9 de cette ouverture centrale 4 disposées de part et d'autre de la portion 7. Cet organe de ventilation 1 comporte une grille de ventilation 1 1 dont le pourtour externe 12 a lui aussi une forme extérieure de couronne sphérique complémentaire de la portion 7 de l'embase 2.
Tel que cela est visible sur la figure 1 , le pourtour externe 12 de la grille 1 1 est emboîté dans la portion 7 présentant sensiblement la forme d'une couronne sphérique de l'ouverture interne 4 de l'embase 2, de sorte que la grille 1 1 et cette embase 2 sont liées l'une à l'autre par une liaison rotule. Un utilisateur peut ainsi agir sur la grille 1 1 pour la positionner de manière à l'incliner afin d'orienter la direction d'éjection du flux d'air d'aération par cet organe de ventilation 1 . This base 2 which has a form of revolution has a central opening 4 forming a vent, and it is connected to a duct 6 for supplying fresh air which is itself connected to an air ventilation system of the vehicle. The inner surface of the central opening 4 has a generally cylindrical shape comprising substantially at mid-length a portion 7 having substantially the shape of a sphere ring, of larger diameter than the cylindrical portions 8 and 9 of this central opening 4 disposed on either side of the portion 7. This ventilation member 1 comprises a ventilation grille January 1 whose outer periphery 12 also has an outer shape of a spherical crown complementary to the portion 7 of the base 2. As can be seen in FIG. 1, the outer periphery 12 of the grid 11 is fitted into the portion 7 having substantially the shape of a spherical crown of the internal opening 4 of the base 2, so that the grid 1 1 and this base 2 are connected to each other by a ball joint. A user can thus act on the grid 1 1 to position it so as to tilt it so as to orient the direction of ejection of the flow of ventilation air by this ventilation member 1.
Cette grille 1 1 qui a une forme générale de révolution, comporte des bras radiaux 13, 14, 16, 17, qui apparaissent plus clairement sur la figure 2. Chaque bras a une forme générale de triangle plan et s'étend depuis la face interne du pourtour 12 jusque à une partie centrale tubulaire 18 qui s'étend selon l'axe de révolution de cette grille 1 1 , et dans laquelle est monté un nébuliseur 19. This grid 1 1 which has a general shape of revolution, comprises radial arms 13, 14, 16, 17, which appear more clearly in Figure 2. Each arm has a general shape of a plane triangle and extends from the inner face from the periphery 12 to a tubular central portion 18 which extends along the axis of revolution of this grid 1 1, and in which a nebulizer 19 is mounted.
Les quatre bras 13, 14, 16, 17 masquent globalement la moitié de la surface de l'ouverture 4, et cette grille 1 1 porte encore un volet obturateur 21 qui est monté rotatif autour du tube central 18. Ce volet rotatif 21 comporte lui aussi quatre bras radiaux triangulaires 22, 23, 24, 26 régulièrement répartis autour de l'axe AX et s'étendant chacun depuis sa périphérie jusqu'à sa région centrale. Ces bras 22, 23, 24, 26 couvrent eux aussi environ la moitié de la surface de l'organe de ventilation 1 . The four arms 13, 14, 16, 17 generally mask half of the surface of the opening 4, and this gate 1 1 still carries a shutter 21 which is rotatably mounted around the central tube 18. This rotary shutter 21 comprises also four triangular radial arms 22, 23, 24, 26 regularly distributed around the axis AX and each extending from its periphery to its central region. These arms 22, 23, 24, 26 also cover about half of the surface of the ventilation member 1.
Le volet 21 est ainsi mobile en rotation sur environ un quart de tour entre une position de fermeture dans laquelle il ferme conjointement avec les bras 13, 14, 16, 17 de la grille 1 1 l'ouverture 4 de façon complète, et une position d'ouverture dans laquelle les bras 22, 23, 24, 26 du volet 21 sont au dessus des bras 13, 14, 16, 17 de la grille 1 1 , pour laisser passer le flux d'air de ventilation. The shutter 21 is thus rotatable about a quarter of a turn between a closed position in which it closes together with the arms 13, 14, 16, 17 of the grid 1 1 the opening 4 completely, and a position opening in which the arms 22, 23, 24, 26 of the flap 21 are above the arms 13, 14, 16, 17 of the grid 1 1, to let the flow of ventilation air.
Le nébuliseur 19 comporte un corps généralement cylindrique engagé et maintenu dans la partie tubulaire 18 de la grille 1 1 , avec une tête de nébulisation 27 qui affleure du côté de la grille 1 1 qui est en aval du flux d'air de ventilation acheminé par le conduit 6. Ce nébuliseur 19 est alimenté en liquide par l'intermédiaire d'un tuyau flexible 28 situé dans le conduit 6, ce liquide pouvant être de l'eau, et il est également connecté à des câbles électriques situés dans le conduit 6 et non représentés. Ce nébuliseur 19 est avantageusement de type piézoélectrique, mais il peut aussi être de tout autre type. The nebulizer 19 comprises a generally cylindrical body engaged and maintained in the tubular portion 18 of the grid 1 1, with a nebulizing head 27 which is flush with the side of the grid 1 1 which is downstream of the flow of ventilation air supplied by the duct 6. This nebulizer 19 is supplied with liquid via a flexible pipe 28 located in the duct 6, this liquid may be water, and it is also connected to electrical cables located in the duct 6 and not shown. This nebulizer 19 is preferably piezoelectric type, but it can also be of any other type.
Lorsque la ventilation est en fonctionnement, les microgouttes issues de la tête 27 sont ainsi générées hors du conduit 6 d'alimentation en air, c'est-à-dire
directement à l'intérieur de l'habitacle du véhicule, de sorte qu'il n'existe pas de risque de condensation d'eau dans les canalisations de ventilation. When the ventilation is in operation, the microdroplets coming from the head 27 are thus generated outside the duct 6 for supplying air, that is to say directly inside the passenger compartment of the vehicle, so that there is no risk of condensation of water in the ventilation ducts.
Par ailleurs, grâce au fait qu'il est directement porté par la grille 1 1 , ce nébuliseur 19 s'oriente avec celle-ci lorsque l'utilisateur ajuste l'inclinaison de cette grille 1 1 , par exemple pour diriger le flux d'air de ventilation vers son visage. Il s'ensuit que le nébuliseur 19 est toujours orienté selon le flux d'air de ventilation, de sorte que l'évaporation des microgouttes en est continuellement favorisée, ce qui est encore accentué par le fait que les nébuliseurs 19 sont généralement très directifs, c'est-à-dire que les microgouttes sont éjectées parallèlement à une même direction. Furthermore, thanks to the fact that it is directly carried by the grid 1 1, this nebulizer 19 is oriented with it when the user adjusts the inclination of the grid 1 1, for example to direct the flow of ventilation air to his face. It follows that the nebulizer 19 is always oriented according to the flow of ventilation air, so that the evaporation of microdroplets is continually promoted, which is further accentuated by the fact that the nebulizers 19 are generally very directional, that is to say that the microdrops are ejected parallel to the same direction.
Globalement, grâce au montage du nébuliseur 19 directement sur la grille d'aération 1 1 , 1e flux d'air et le flux de microgouttes sont toujours orientés selon la même direction, ce qui favorise très fortement l'évaporation de ces microgouttes.
Overall, thanks to the mounting of the nebulizer 19 directly on the ventilation grid 1 1, the air flow and the flow of microdroplets are always oriented in the same direction, which greatly promotes the evaporation of these microdrops.
